Embodiment 1

[0034] Embodiment 1 rich organic selenium vegetable cultivation example

[0035] In a vegetable base, according to the cultivation steps of organic selenium-rich vegetable seedlings under the method of field border seedling cultivation, 6 groups of 1-mu field-use cabbage seedlings were cultivated, and different amounts of nano-selenium plant nutrients were applied to cultivate organic selenium-rich cabbage seedlings, and transplanted Harvest organic selenium-rich cabbage after planting in the field. And randomly sampled from organic selenium-rich cabbage for inspection. Wherein each group applies the quality of nano-selenium plant nutrient, and total selenium content and organic selenium ratio in Chinese cabbage after harvest, as shown in the table below:

[0036]

[0037] Note: The total selenium content in the table is tested according to the national standard method GB / T12399-1996, and the organic selenium content is determined by the subtraction method.

Embodiment 2

[0038] Embodiment 2 is rich in organic selenium vegetable cultivation example

[0039] In a vegetable base, according to the cultivation steps of organic selenium-rich vegetable seedlings under the method of field border seedling cultivation, 6 groups of 1-mu field tomato seedlings were cultivated, and different amounts of nano-selenium plant nutrients were applied to cultivate organic selenium-rich tomato seedlings. Harvest organic selenium-rich tomatoes after planting in the field. And randomly sampled from organic selenium-rich tomatoes for inspection. Wherein each group applies the quality of nano-selenium plant nutrient, and total selenium content and organic selenium ratio in tomato after harvest, as shown in the table below:

[0040]

[0041] Note: The total selenium content in the table is tested according to the national standard method GB / T12399-1996, and the organic selenium content is determined by the subtraction method.

Embodiment 3

[0043] In a vegetable base, according to the cultivation steps of organic selenium-rich vegetable seedlings under the method of growing seedlings in the field, 6 groups of 1-mu field-use pepper seedlings were cultivated, and different amounts of nano-selenium plant nutrients were applied to cultivate organic selenium-rich pepper seedlings, and transplanted After being planted in the field, the organic selenium-rich peppers are harvested. And randomly sampled from organic selenium-rich peppers for inspection. Wherein each group applies the quality of nano-selenium plant nutrient, and total selenium content and organic selenium ratio in capsicum after harvest, as shown in the table below:

[0044]

[0045] Note: The total selenium content in the table is tested according to the national standard method GB / T12399-1996, and the organic selenium content is determined by the subtraction method.

Abstract

The invention discloses selenium-rich vegetable seedlings, a cultivation method thereof and vegetables produced rich in organic selenium. The selenium-rich vegetable seedlings have a total selenium content of 18-1620 microgram / piece when being transplanted. The method comprises the steps of adding nano-selenium plant nutrient into nursery soil or a nursery land during vegetable seedling raising phase, and cultivating selenium-rich vegetable seedlings according to a vegetable seedling raising method. The vegetables rich in organic selenium have a selenium content of 10-300 microgram / kg, with an organic selenium content of over or equal to 80 percent. The invention have the advantages that the vegetables are rich in selenium, the overall selenium content is uniform, and the ratio of organic selenium is improved by the method, thereby solving the problem of selenium content stability in different batches of vegetables in the prior art, ensuring uniform selenium content in the vegetables, and realizing standardized scale production.

Description

technical field [0001] The invention relates to vegetable seedlings for producing vegetables rich in organic selenium and a cultivation method for the vegetable seedlings. The utility model belongs to the field of agricultural fertilization and agronomic technology. Background technique [0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide a variety of vitamins and minerals necessary for the human body. Especially in China's dietary structure, vegetables account for a large proportion. The planting of common vegetables can mostly be realized by transplanting seedlings. [0003] Selenium, element symbol Se, is an essential trace element for the human body and is the active center of glutathione peroxidase (GSH-Px). It has biological properties such as anti-cancer, anti-aging (anti-oxidation), improving human immunity, and antagonizing heavy metals. Selenium in the food chain mainly comes from soil. If the distribution of seleni...
